Traditional Pythagorean numerology doesn't use a clock time in calculations. But it does use dates, generally either to reveal the most likely resonances for that particular date or to determine the events and circumstances most likely to occur in the future for something that started on that date, its life path.

If that date is considered to be the date your relationship started, then the calculated result would be assigned to the life path of your relationship. The life path number then is the number 8. The number 8 is compatible with both the number 1 and the number 3 noted in your question.

That only means compatibility in that one area. And compatibility does not bode well or unwell; it's just a statement of compatibility. Incompatibility often leads to a deeper relationship because the incompatibility introduces alternate energies that can be experienced and assimilated.

Your relationship depends more on what the two of you do and don't do, how you relate, than does the energy represented by any number. In other words, your future is created by what you do today; it doesn't just suddenly manifest full blown.

That said, the energy represented by numbers do have a subtle influence. But it is subtle. Free will always has precedence.

Your life path numbers, 1 and 3, represent compatible energies. For more compatibility revelations, use the Marriage Compatibility calculator.
